Daft Acton, who was living in Troon, tested positive for Stanozolol, a synthetic steroid, in August.

Now he had been banned from the sport for three years and nine months.

Scottish Rugby’s chief medical officer, Dr James Robson said: “We have a robust process in place for those who wish to by-pass the anti-doping rules, this is an intelligence led system which has resulted in this particular case in finding a drugs violator.”

Acton injected the drug which is named on the 2017 World Anti-Doping Agency Prohibited List and is banned at all times.

Testers arrived at the training ground in Troon on August 10 to nab him and get a urine sample.
